Post-nasal drip (PND), also known as upper airway cough syndrome (UACS), occurs when excessive mucus is produced by the nasal mucosa. The excess mucus accumulates in the back of the nose , and eventually in the throat once it drips down the back of the throat.
Having green, yellow, or thickened phlegm (sputum) does not always indicate the presence of an infection. Also, if an infection is present, the color of the phlegm (sputum) does not determine whether a virus, a bacterium or another pathogen has caused it. Simple allergies can also cause changes in the color of the mucus. [1]
Rhinorrhea is characterized by an excess amount of mucus produced by the mucous membranes that line the nasal cavities. The membranes create mucus faster than it can be processed, causing a backup of mucus in the nasal cavities. As the cavity fills up, it blocks off the air passageway, causing difficulty breathing through the nose.
A chronic cough can be due to many things from asthma to post-COVID-19. Here's how to figure out why you can't stop coughing and how to treat it.
“A productive cough is a cough that produces phlegm,” Dr. Youssef says. But a non-productive cough is more dry, says John M. Coleman III, M.D., a pulmonary and critical care specialist with ...
[35] [40] Excess mucus shows itself as a chronic productive cough and its severity and volume of sputum can fluctuate in periods of acute exacerbations. [35] In COPD, those with the chronic bronchitic phenotype with associated chronic excess mucus, experience a worse quality of life than those without. [35] [41]
Along with a runny nose and sore throat, green phlegm is another cold-like symptom of COVID-19. Interestingly, the color of the mucus is an important indicator when it comes to infection.
The clinical presentation of plastic bronchitis beyond expectoration of casts includes a productive cough, dyspnea, fever and wheezing. Focal wheezing is a characteristic, if not specific, physical examination finding. If the casts completely obstruct the airway, breath sounds will be decreased and dullness will be present with percussion.
